Is there a possible link with code p3040 and the transmission

Asked by Jun 20, 2012 at 01:27 AM about the 2006 Jeep Liberty Sport 4WD

Question type: Maintenance & Repair

2 days ago my check engine light came on and the code was
p3040 and since then it has stalled twice and the transmission
feels like it jerks for like 2-3 seconds sometimes when I
exselerate, it feels like a jerking that's the best way to describe
it could that also be from the censor that I need to replace
which I'm doing tomorrow.

P3040 indicates that a problem was detected in the camshaft position sensor circuit. Since it says circuit, that means the problem could lie in any part of the circuit - the sensor itself, the wiring, or the PCM. I'd say this is your stalling issue and not the tranmission.

Thank u for the advise I didn't think that would help but I was hoping, the transmission is only 8 months old in my truck as it is, I bought the jeep back in Oct from a dealer and it went about 6 hours after a bought it.
